In 2023, after our company purchased High-Speed-CNC of YASDA, a mold factory in the UAE placed an order with us. The order was 13 sets of multi-cavity ultra precision mould bases. The customer has multiple factories in India and Dubai, and has high precision requirements for the mold. We sent reply drawings to customers for each set of mould bases to confirm and negotiate processing requirements such as technology, tolerances, and accessories. Although it was our first collaboration, the process of adaptation was relatively smooth and we were able to quickly cooperate and solve any problems encountered. After nearly two months, all products have been shipped safely.

This visit is the first time that the client has visited our company after cooperating with us. The main purpose is to inspect our equipment and evaluate the possibility of increasing cooperation in the future. The customer mainly visited the steel milling and CNC workshop, and highly appreciated our YASDA brand high-speed CNC machine. Our company also stated that this machine produces most of the customer's products. In addition, the customer also stated that the more than 10 sets of mold blanks received earlier have been put into use and the quality is very good. We also discussed the issue of steel being prone to rusting and mold base components. Our company will put more effort into vacuum packaging and anti rust oil application, and the accessories will also be inspected before being installed on the mold base. The customer is very satisfied with this trip and expressed that they will deepen cooperation with our company.

Double Injection mold base, or Two-color mold base, or Bi-color mold base. In the dual color injection molding process, this type of mold is designed to sequentially or simultaneously inject two different colored plastic materials into a single mold, thereby producing plastic products with dual or multi-color appearances.





Characteristic

1. Multi cavity design: usually with two or more injection cavities for simultaneous or continuous injection of plastic of different colors or materials. Usually composed of multiple layers of structure. Each layer has different materials or colors, and through the combination of mold bases and injection molding process, the multi color or multi material effect of the product can be achieved. The multi-layer structure enables the dual color non-standard mold base to have a wider range of applications, which can meet the color and material requirements of different products.



2. Complex structure: Due to the need to handle injection molding and bonding of two materials, the structure of the mold base is relatively complex, including rotating mechanisms, sliders, ejection systems, etc. Some parts of the double injection non-standard mold base may have adjustable structures. By adjusting the position or parameters of these parts, fine-tuning of product size, shape, and color can be achieved. The adjustable structure increases the flexibility and adaptability of the mold base, which can meet the personalized needs of different customers.



3. High precision requirements: In order to ensure the appearance quality and dimensional accuracy of dual color products, the manufacturing and installation of the mold base need to meet high precision standards. The double injection non-standard mold base emphasizes precision fit in structural design. The various components of the mold base need to be precisely matched to ensure the stability and accuracy of the mold during use. Precision fitting can reduce friction and wear of the mold during use, improve the service life and manufacturing accuracy of the mold.





Application of mould base

1. Consumer goods: such as phone cases, electronic product accessories, toys, etc., which usually require attractive appearance and feel.



2. Automotive components: Automotive interiors, buttons, switches, etc., two-color injection molding can provide better visual effects and tactile experience.



3. Medical devices: Some medical devices and components also use two-color injection molding technology to improve product recognition and usage safety.





Points for attention

When designing and manufacturing a "Double Injection mold base", special attention should be paid to the following points:



1. Material selection: The two injection molding materials need to have good compatibility and bonding to ensure smooth flow during the injection molding process and the final quality of the product. And it is usually made of high-strength materials to ensure the stability and durability of the mold during use. High strength materials can withstand greater pressure and stress, while also possessing good wear and corrosion resistance. This makes the two-color non-standard mold base suitable for various complex production environments and process requirements



2. Temperature control: During the double color injection molding process, it is necessary to accurately control the temperature of the mold and injection molding machine to ensure the injection quality of different materials.



3. Mold maintenance: Due to its complex structure, the maintenance and upkeep of molds need to be more meticulous and frequent to ensure their long-term performance and stability.



In summary, the "Double Injection Mold Base" is a key component in the double injection molding process, and its design and manufacturing have a significant impact on the final quality and appearance of the product. In practical applications, it is necessary to choose the appropriate mold structure and injection molding process based on specific product requirements and production conditions.

The hardness and wear resistance of mold steel are closely related. Generally speaking, the higher the hardness, the better the wear resistance. High hardness makes the surface of mold steel more resistant to friction and wear. But hardness is not the only factor, the material's organizational structure and other factors can also affect wear resistance. However, high hardness can usually greatly improve the wear resistance of mold steel.

What are the requirements for the performance of steel in automotive molds? Firstly, it has high hardness and can withstand high-intensity stamping without deformation. Secondly, good wear resistance ensures the service life of the mold. Thirdly, sufficient toughness is required to prevent the mold from cracking during use. In addition, good processing performance facilitates the processing into complex mold shapes. At the same time, it also needs to have good thermal stability to adapt to high-temperature processing environments.
